TFTP server in Windows 10

Is there a native TFTP server in Windows 10?

The Ethernet switches that I manage can copy the configuration to a TFTP server. I need to save copies of the configurations and compare before and after each vendor firmware update. So I'm seeking such a server.

 

TFTP Server not working

I have a microsoft surface pro and no matter what TFTP server I download and use I cannot transfer files from my switch. The TFTP server works fine from my HP laptop and Dell but, not on the surface. Did a netstat -aon to see the PID associated with the
TFTP server I have downloaded and it looks to be correct. On the switch it shows error accessing image and on the TFTP it show no activity during download attempt. TFTP client has been turned on and the firewall and anti-virus have been disabled. Has anyone
ran into this issue and found a solution?
